This is the Advanced [[Atmospherics]] Guide. If you're looking for a [[Atmospherics#ATMOS_QUICK_SETUP|Quick Setup Guide, see this]]. If you're ready to really learn about the atmospheric system, read on. By reading this guide you will learn how to transform Atmos from a waste of space to an actually useful addition. We will go through all kinds of theory, so this may be tough, but it will also ensure you know exactly how and more importantly '''why''' Atmos works the way it does, making you ready for all kinds of situations. | This is the Advanced [[Atmospherics]] Guide.

Nitrogen. Soaks up heat in the air, and lowers the temperature of a fire. By association, it can very quickly lower the temperature of a fiery rupture to the point where the flames self-extinguish. Proof of this can be seen if you go down to the incinerator with a can of burnmix, and a can of 20% burnmix and 80% N2. The N2 contaminated fire will not burn nearly as hot or as well. This is why the Toxins guide recommends opening up a can of N2 to the air, it can and will save your life if there's a rupture. Due to the vastly higher | Nitrogen.

This is why the Toxins guide recommends opening up a can of N2 to the air, it can and will save your life if there's a rupture. Due to the vastly higher heat capacity, N2 is incredibly better at stopping fires: in 100 kPa of N2/O2 80/20 and 100 kPa of O2 100, the N2/O2 is effectively 12200 kPa as opposed to 100 kPa in terms of soaking up heat and it doesn't allow the fire to grow in size as quickly, the combination of which can even lead to non-permanent ignition sources being snuffed out by themselves. | ||

Carbon Dioxide. An invisible, heavy gas, CO2 is one of the first and fastest gases the scrubbers suck out of the air. It chokes people effectively and quickly, and if you can be bothered to set the alarms up, will result in a invisible room that kills those in it. Takes some setup and can be very, very annoying. The emote for this at low levels is | Carbon Dioxide. An invisible, heavy gas, CO2 is one of the first and fastest gases the scrubbers suck out of the air.

Sadly, without either Volume or Moles, it's not useful in game and is here for the theory. | Where '''R (ideal, or universal, gas constant) = 8''', the following are linked by this equation.

This is bloody annoying, because though the Air Alarms pick them up as "High Concentration of Unknown Particles Detected", they are impossible to suck down to Atmos. Spacing the entire affected air is, as far as I know, the only real "cure". There is a viable way to clean this, if you can safely cordon off the area. Detonating a welding fuel tank usually cuts a hole to space on the tile beneath it, and thus if you set your internals on and wear a fire suit, is an highly unsafe but effective way of draining the air. It is also one of the few ways to destroy pipes which are at a high pressure and thus can be a useful emergency cut-off if there is plasma irrevocably linked to distribution. It does KO you, do damage, and can make a space tile, which means without internals and a fire suit it can kill you. Caution is advised. | ||
